“…One of these factors is the erosion of the river walls by water so that rock slope buildings on the river walls can function to prevent erosion and overflow of water. The function of the rock slope is to control river bank erosion and control excessive rainwater so it does not overflow and acts as a barrier to cliffs (Gunawan, 2000). The use of village funds for the development of the Village is quite beneficial for the community, both in supporting economic activities and access to production sources or the comfort and security of the community in carrying out activities, so the village government must pay more attention to or prioritize development that is sustainable urgent for the safety and security of the local community.…”

This study aims to determine how village funds are managed and how the Government's efforts are in improving the community's economy in Ranjok village, Gunung Sari sub-district, West Lombok district. This study used a qualitative research method with a case study approach. Data was obtained through observation, interviews, and documentation. Informants are optional by using a purposive sampling technique. Data analysis by reducing, displaying, and presenting coded data. The results of the study found that the management of DD in Ranjok village was prioritized in development, such as road repairs, football field construction, Talaud, repair of irrigation channels, and others. In addition to development, it is also in the form of establishing BUMDes which is engaged in selling Stationeries and photocopies, and finally, the distribution of Direct Cash Assistance (BLT) to the community. At the same time, the Government's efforts to improve the community's economy are by holding training or empowering the community with their potential to improve skills/expertise, such as holding carpentry training and catering training.

“…Perbedaan tersebut terjadi karena pola aliran pada saluran berbelok dan saluran aliran tidak seragam yang tidak sama akibat adanya faktor pengaruh dari kecepatan aliran dan juga luas penampang saluran. Karakteristik aliran pada belokan saluran terbuka, menunjukkan trend/pola kecepatan minimum terjadi di dekat dasar dan bertambah besar ke arah permukaan aliran (Purnama, 2017). Kecepatan aliran mengalami percepatan dan perlambatan ketika melalui belokan, dimana kecepatan aliran meningkat di sisi dalam belokan (inner bank) ketika melewati awal belokan dan kecepatan menurun saat melewati akhir belokan dan sebaliknya kecepatan menurun pada sisi luar belokan (outer bank) ketika melewati awal belokan dan mengalami peningkatan di sisi dalam belokan saat melewati akhir belokan.…”

The flow that has a free surface is a form of water flow in an open channel. However, the flow of water in open channels is not always the same, due to topographic differences along the channel. This results in a difference in the value of the flow velocity and the value of the discharge. Therefore, it is necessary to conduct a study on discharge on flow velocity and wet cross-sectional area in different types of channels. The type of channel used in this study is a turning channel and a non-uniform channel, both of which are located in the Yogyakarta Mataram Channel. The data used is secondary data obtained from previous research in the form of channel cross-section data and flow velocity in each channel. The results of the analysis show that the discharge in both types of channels has the same curve pattern as the average flow velocity curve. Then the suitability of the two curve patterns is influenced by the value of the wet cross-sectional area, where the greater the value of the wet cross-sectional area, the greater the value of the discharge, and vice versa.Aliran yang memiliki permukaan bebas merupakan salah satu bentuk aliran air pada saluran terbuka. Meskipun demikian aliran air pada saluran terbuka tidaklah selalu sama, karena adanya perbedaan topografi di sepanjang saluran. Hal tersebut mengakibatkan adanya perbedaan nilai kecepatan aliran dan nilai debit aliran. Oleh karenanya perlu dilakukan suatu penelitian mengenai debit aliran terhadap kecepatan aliran dan luas penampang basah pada jenis saluran yang berbeda. Jenis saluran yang digunakan pada penelitian ini yaitu saluran berbelok dan saluran aliran tidak seragam, yang mana kedua jenis saluran tersebut berlokasi di Saluran Mataram Yogyakarta. Adapun data yang digunakan adalah data sekunder yang diperoleh dari penelitian sebelumnya berupa data penampang saluran dan kecepatan aliran di masing-masing saluran. Hasil analisis yang didapat bahwa nilai debit aliran di kedua jenis saluran tersebut memiliki pola kurva yang sama dengan pola kurva kecepatan aliran reratanya. Kemudian sesuai atau tidaknya kedua pola kurva tersebut dipengaruhi oleh besarnya nilai luas penampang basahnya, yang mana semakin besar nilai luas penampang basah maka semakin besar nilai debit alirannya, begitu pula sebaliknya.

“…Kelokan sungai menyebabkan kecepatan aliran air sungai menjadi menurun. Kecepatan aliran sungai yang menurun menyebabkan tingginya endapan yang terjadi sehingga menaikkan nilai dari zat pencemar (Purnama & Nuraini, 2017).…”

The quality of the waters is influenced by the activities of living things around it, one of which is the activity of small industries that have not treated their wastewater optimally due to a lack of capital. One of the small industries that we often encounter and has the potential to contaminate is the chicken slaughterhouse industry (RPA), because RPA waste water contains high organic matter. This study used a case study approach to analyze the distribution of RPA wastewater on river water quality in Kalitirto Village, Berbah District, Sleman Regency. Data collection was carried out by taking samples of RPA wastewater, RPA groundwater, and river water. Tests were carried out in situ (pH) and in the laboratory (BOD, COD, TSS, total oil and fat). The measurement results of RPA liquid waste exceed the quality standard. The quality of river water before and after RPA is different. The result of the correlation coefficient is -0.829, meaning that the further away the RPA waste is in river water, the smaller the pollution index value. The probability result is 0.085, meaning that the relationship between the presence of liquid waste and the pollution index is not significant. The distribution of RPA waste does not occur in river water but enters the groundwater.
